To all whom t may concern:

Be it known that I, CHARLES EDWARD OLIVER, a subject of the King ofGreat Britain, and a resident of London, England, have invented certainnew and useful linprovements in Wheels for Road-Vehicles, of which thefollowing is a specification.

' This invention relates to improvements in wheels for road vehicles,and has reference to wheels including a tire carrying rim coniprisiiigcircular and substantially similar parts or disks provided with meanswhereby the parts can be arran 'ed and secured on the hub. A usual methoof constructingsuch wheels is to secure one of the parts .to t-he huband rely upon bolts securing the parts.

togetherv at the felly to keep the wheel rigid.

`With this construction, however,' the tend.

ency of the parts to move/ relatively has to be restrained solely by thebolts at the felly, and unless very substantial bolts arel eniployedthey are liable to become bent and so prevent the ready disassembly ofthe wheel.

`The present invention consists-of an improved construct-ion of suchwheels, an important featureof which is that the two or more parts ofthe wheel are secured positively to rotate with the hub as well as beingrigidly secured to eachother so as to obviate any possibility ofrelative movement 'of the parts and to relieve the bolts connecting thetwo or more wheel parts at the fellyfrom the strain consequent upon thetendency of the two or more parts to move relatively. This involves theprovision of a plate rigidly secured to rotate with the hub and providedwith a series of short bolts for securing the inner part of the Wheel tothe hub and a series of long bolts adapted to pass through both or allthe wheel parts. Further features of the invention consist in theprovision ofipacking rings or gaskets between the two or more wheelparts to insure watertight joints and a .special arrangement of bushingin one of the wheel parts for receiving the bolts which pass through thefelly o'f the wheel parts.

By lmeans of the foregoing construction great rigidity is secured andthe removal of the outer half or parts of the wheel can be readilyeffected.

The invention willbe more clearly underv stood from the followingdescription in relation to the accompanying drawingswherein is s'hown'a`wheel constructed in accordance with my invention; but it will be ap-vvpreciated that,` thoughd have depicted ay wheel having wooden spokes,and so assembled that the spokes of the two halves are coincident, thatis to say, lie one behind the other, I do not confine myself to thisforni' of wheel, and that the invention is applicable to wheels carryingspokes of other material,

and that the two parts forming the wheel may be so assembled that theirrespective spokes may be differently arranged in relal tion to eachother.

While l have illustrated the wheel made up of two sections, it will beunderstood that a greater number of sections may be used if desired, iiiorder to accommodate different semb y showing in dotted lines theposition 4t is an enlarged `view of a special occupied by the wheel whenassenibied. Fig. form of tapered bolt. \Fig. 5 is a perspective view ofa portion of the rim and felly. l Fig. 6 is a cross sectional view ofthe rini taken through one of the binding bolts. Referring to thesedrawings and more particularbT to lligs. 'l and 2 the numeral 1designates the inner half of one of the wheels, and the numeral 2 theouter half. Each half comprises, a boss 3 to it on the hub 4, spokes 5radiating therefrom and half of a rim 6 and beading 7. The hub 4 isfitted with a circular plate or disk 8 cut with, or exceed, the boss 3of the inside half 1 of the wheel. This plate or disk 8 which may formpart of the drum, and in any case must be rigidly associated withA thehub, carries bolts which are alternately long and short, the long .boltsare indicated by the numeral 9 and the short by the numeral 10.l

These bolts9 and 10 are screw threaded, but

at their ends only so that they may accommodate their r11-its and `yetcause as little friction as possible when it is required that the outerhalf 2 be moved over them. They are placed in a circle around, andperpendicular to, the outside face of the plate or disk 8 and are atsuch a distance from the center of said plate or disk 8 that the longand short to an enlarged scale in Fig. fl. This bolt is `wheel may`carried by it coincide with the spokes carried by the irst half 1.`bolts lie in holes countersunk in the half bolts 9 and 10 register withholes 11 and 12 cut in the bosses 3 of the two halves of the wheel 1 and2 respectively, the short bolts 10 with the holes 12 of the inside half1 of -said wheel, and the` longbolts 9 with the pass through both thehalvesl -1 and 2 of the wheel.

holes 11 which As beforementioned the bolt holes in the second half 2 ofthe be so placed that the spokes 5 The nuts 13 .of the 1 so that the twohalves may fit tightly up against one another.

A modified form of long bolt 14 is shown tapered for slightlymore of itslength than registers with the half 2 of the wheel, with Q the object ofallowing the part 2 to be more rims of the two halves 1 formed with afelly 6. bolts 15 suitably spaced easily removed.

What I claim and desire to secure by Let ters Patent is 1. A wheel madeup of two sections each comprising a folly, a central open boss and'integral spokes connecting the felly and boss, combined with a hub,means securing the inner boss to said hub, means securing the inner andouter bosses to said hub, and means near the periphery of the wheel forsecuring the two sections together.

2. A wheel made up of two sections each comprising a felly, a centralopen boss, and spokes connecting the felly and boss, com bined with ahub, a series of bolts securing the inner boss to the hub, a series oflonger bolts passed threugh both bosses and secured to the hub, andbolts near the periphery fastening the two sections together.

3. A. wheel made up of two sections each comprising a felly, centralopen boss, and integral spokes, combined with hub and an attaching plateon the hub, a series of short bolts attaching said plate to the innerboss, a series of longer bolts passed through both bosses and securingthe outer boss to the plate, and bolts near the periphery of the wheelsecuring the two sections together.

a. A vehicle wheel including a tire carrying rim, and comprising a hubplate, a series of short -bolts screw threaded at their outer ends andrigid with said plate, series of longer bolts screw threaded at theirouter ends and rigid with said plate, a wheel portion having openingsand countersunk recesses to 1it over said short bolts and nuts in therecesses on the bolts, a second wheel section having bolt openings andrecesses and nuts on the longer bolts located in Asaid recesses, and agasket interposed between said wheel portion and section.

ln testimony whereof l aliix my signature.

CHARLES EDWARD oLivnn.
